I like those but may lean towards something that doesn’t need cutting. I had a friend reach out to me that builds custom cars. He had me send a link for the Rust Buster brand I was looking at. He offered to do it no charge. It has to be towed to his shop, he also owns a fleet of tow trucks, again no charge. I took care of him several times over the years with some left over concrete and never asked for anything in return, and he won’t let me forget it.
